Bacterial wilt, which is a major soil-borne disease with widespread occurrence, poses a severe danger in the field of tobacco production. However, there is very limited knowledge on bacterial wilt-induced microecological changes in the tobacco root system and on the interaction between Ralstonia solanacearum and fungal communities in the rhizosphere soil. Thus, in this study, changes in fungal communities in the rhizosphere soil of tobaccos with bacterial wilt were studied by 18S rRNA gene sequencing. The community composition of fungi in bacterial wilt-infected soil and healthy soil in two tobacco areas (Gengma and Boshang, Lincang City, Yunnan Province, China) was studied through the paired comparison method in July 2019. The results showed that there were significant differences in fungal community composition between the rhizosphere soil of diseased plants and healthy plants. The changes in the composition and diversity of fungal communities in the rhizosphere soil of tobaccos are vital characteristics of tobaccos with bacterial wilt, and the imbalance in the rhizosphere microecosystem of tobacco plants may further aggravate the disease.

Varietal difference in the occurrence of grey leaves in upland diverted from paddy field were investigated with several flue-cured tobacco varieties in Korea. Grey leaves caused by Fe, Mn and Cl toxicity were occurred in all varieties used in this experiment. The variety, NC82 and KF113, however, were more sensitive than other varieties to the toxicity. It's revealed that grey leaves had little effects on the contents of total sugar, nicotine and total nitrogen. NC82 and KF113 were increased in the ratio of occurrences in the paddy soils which had a tendency to concrete with the passage of days after transplanting. NC82 showed high occurrences of grey leaves in each of variety used and it was estimated that this variety had a traits of easy occurrences of grey leaves, and it might be presumed that there would be a close connection between the ratio of occurrence and amounts of absorbed causal materials accumulated in plants and tobacco varieties on the occurrence of grey leaf tobacco.

This study was made of the effects from exposure to air temperature and amount of solar radiation during the wilting period on the sunburn of burley tobacco. Tobacco stalks were cult with one hour interval from 8:00 to 16:00, and were left on the field to expose to weather, and tobacco single leaf placed under 4 temperatures regimes in indoor. Sun-burn of the leaves was occurred when the leaves were exposed to temperature higher than 33$^{\circ}C$, and to solar radiation more than 800w/$m^2$ between 11:00-15:00 in a day during the curing season. The leaf temperature was increased until 52$^{\circ}C$ under the weather condition. The tobacco leaves were also burned without solar radiation when the leaves were exposed to high temperature until 5$0^{\circ}C$ of leaf temperature. Sun-bum was increased at upper leaves and at higher moisture content of leaf.

This experiment was conducted to find out the optimum fertilization level and topping depth for flue-cured tobacco in the fields which chinese cabbage and red-pepper were cultivated. The fertilization level were 0, 25, 50, 75kg per l0a as tobacco compound fertilizer and the topping depth were topping floral axis, topping under the second leaf frp, axos and the fourth leaf from floral axis. In order to product good quality tobacco leaves in the fields which vegetables were cultivated, the optimum amount of tobacco compound fertilizer was recommended 50-75kg per l0a for the field of the chinese cabbage cultivated. and 75kg per l0a for the field of the red-pepper cultivated. The optimum topping depth was desirable at topping under second leaf from floral axis for good leaf quality in chinese cabbage and red-pepper cultured field.

Soil residues in a tobacco field yearly treated with a soil insecticide, Heptachlor, was analyzed by GLC equipped with electron capture detector(ECD). In addition, translocation of the heptachlor residues into two staple vegetables, radish and chinese cabbage was also studied under field conditions. The results were summarized as follows; 1. The Heptachlor residues in the soil of tobacco plots were less than 0.010 ppm. 2. The Heptachlor residues in radish and chinese cabbages cultivated in the tobacco plot were also below 0.010 ppm. 3. Amount of Heptachlor residues translocated into the vegetables were not related to the concentrations of the residues in the soil.

Introduction: Tobacco use is a leading cause of deaths and disabilities in India, killing about 1.2 lakh people in 2010. About 29% of adults use tobacco on a daily basis and an additional 5% use it occasionally. In Odisha, non-smoking forms are more prevalent than smoking forms. The habit has very high opportunity cost as it reduces the capacity to seek better nutrition, medical care and education. In line with the WHO Framework Convention on Tobacco Control (FCTC), the Cigarettes and Other Tobacco Products Act (COTPA) is a powerful Indian national law on tobacco control. The Government of Odisha has shown its commitment towards enforcement and compliance of COTPA provisions. In order to gauge the perceptions and practices related to tobacco control efforts and level of enforcement of COTPA in the State, this cross-sectional study was carried out in seven selected districts. Materials and methods: A semi-structured interview schedule was developed, translated into Odiya and field-tested for data collection. It mainly contained questions related to knowledge on provisions of section 4-7 of COTPA 2003, perception about smoking, chewing tobacco and practices with respect to compliance of selected provisions of the Act. 1414 samples were interviewed. Results: The highest percentage of respondents was from the government departments. 73% of the illiterates consumed tobacco as compared to 34% post graduates. 52.1% of the respondents were aware of Indian tobacco control laws, while 80.8% had knowledge about the provision of the law prohibiting smoking in public places. However, 36.6% of the respondents reported that they had 'very often' seen tobacco products being sold 'to a minor', while 31.2% had seen tobacco products being sold 'by a minor'. In addition, 24.8% had 'very often' seen tobacco products being sold within a radius of 100 yards of educational institutions.

This study was conducted to obtain basic information for varietal difference of leaf breakdown in field of flue-cured tobacco at Taegu Experiment Station, Korea Ginseng & Tobacco Research Institute in 1987. The experiment was designed in randomized block with 3 replications, data ware analysed as Split split-plot design. Main plots were varieties, sub-plots were leaf positions, 4, 5 and 6th from bottom, and each sub-plot was divided into 3 parts with distance of midrib, 7 10 and 13em from stalk. Four varieties, NC 95, NC 2326, NC 82 and BY 4 were transplanted in 15 April, and measured the weight of leaf breakdown by artificially weighted in 5 June. The results obtained are as follows : 1. Weights of leaf breakdown according to leaf position, NC 95 were lower as 358-5799 than those of other varieties as 555-597g, were not significantly different regardless of varieties. 2. Weights of leaf breakdown in relation to distance of midrib from stack, NC 95 were lower as 309-419g than those of other varieties as 472-710g. 3. Weights of leaf breakdown were significantly different according to distance of midrib from stalk, and not significantly different according to leaf position under the same distance of midrib from stalk regardless of varieties.

During the screening of antiviral substances having inhibitory effects on tobacco mosaic virus (TMV) infection to tobacco plants, we found a bacterial isolate KTGBP10, which was identified as a Stenotrophomonas sp., strongly inhibited the infection of TMV. When the culture filtrate from KTGBP10 was applied on the upper surface of leaves of Xanthi-nc tobacco plants at the same time or 24 hours before TMV inoculation, almost complete inhibition of TMV infection was achieved. And $40\%$ inhibition was shown with application of the culture filtrate to the under surface of leaves. In field trials, transmission of TMV from diseased seedlings to the healthy ones during transplanting work was reduced by $87.1\~92.6\%$ when the culture filtrate or cell suspension was sprayed onto the tobacco seedlings, cv. NC82, 24 hours before transplanting. No toxic effect was observed on the tobacco plants. When the broth filtrate of KTGBP10 was supplied by soaking through the cut-leaves before and/or after virus inoculation, the TMV infection was also inhibited by $50.4\~65.3\%$.

The potato tuber moth (Phthorimaea operculella Zeller ) was surveyed for its distribution and damage to tobacco plants in field. The insect was found in all four localities examined ; Dalseong and youngdeog of Gyeongbuk Province, and Boseong and Jindo island of Cheongnam Province. About half of the tobacco plants examined contained the larvae with the highest level (76.7%)of larvae infestation in the Jindo island. In a given tobacco plant the larvae were concentrated on the first three leaves, from bottom, with 82.4 5 of the total number, and a single leaf usually has one to three larval.
